40 CFR 60.104a - Performance tests.

(a) The owner or operator shall conduct a performance test for each FCCU, FCU, sulfur recovery plant and fuel gas combustion device to demonstrate initial compliance with each applicable emissions limit in § 60.102a and conduct a performance test for each flare to demonstrate initial compliance with the H2S concentration requirement in § 60.103a(h) according to the requirements of § 60.8. The notification requirements of § 60.8(d) apply to the initial performance test and to subsequent performance tests required by paragraph (b) of this section (or as required by the Administrator), but does not apply to performance tests conducted for the purpose of obtaining supplemental data because of continuous monitoring system breakdowns, repairs, calibration checks and zero and span adjustments.

(b) The owner or operator of a FCCU or FCU that elects to monitor control device operating parameters according to the requirements in § 60.105a(b), to use bag leak detectors according to the requirements in § 60.105a(c), or to use COMS according to the requirements in § 60.105a(e) shall conduct a PM performance test at least annually (i.e., once per calendar year, with an interval of at least 8 months but no more than 16 months between annual tests) and furnish the Administrator a written report of the results of each test.

(c) In conducting the performance tests required by this subpart (or as requested by the Administrator), the owner or operator shall use the test methods in 40 CFR part 60, Appendices A-1 through A-8 or other methods as specified in this section, except as provided in § 60.8(b).

(6) For process heaters with a rated heat capacity between 40 and 100 MMBtu/hr that elect to demonstrate continuous compliance with a maximum excess oxygen limit as provided in § 60.107a(c)(6) or (d)(8), the owner or operator shall establish the O2 operating limit or O2 operating curve based on the performance test results according to the requirements in paragraph (i)(6)(i) or (ii) of this section, respectively.

(i) If a single O2 operating limit will be used:

(A) Conduct the performance test following the methods provided in paragraphs (i)(1), (2), (3) and (5) of this section when the process heater is firing at no less than 70 percent of the rated heat capacity. For co-fired process heaters, conduct at least one of the test runs while the process heater is being supplied by both fuel gas and fuel oil and conduct at least one of the test runs while the process heater is being supplied solely by fuel gas.

(B) Each test will consist of three test runs. Calculate the NOX concentration for the performance test as the average of the NOX concentrations from each of the three test runs. If the NOX concentration for the performance test is less than or equal to the numerical value of the applicable NOX emissions limit (regardless of averaging time), then the test is considered to be a valid test.

(C) Determine the average O2 concentration for each test run of a valid test.

(D) Calculate the O2 operating limit as the average O2 concentration of the three test runs from a valid test.

(ii) If an O2 operating curve will be used:

(A) Conduct a performance test following the methods provided in paragraphs (i)(1), (2), (3) and (5) of this section at a representative condition for each operating range for which different O2 operating limits will be established. Different operating conditions may be defined as different firing rates (e.g., above 50 percent of rated heat capacity and at or below 50 percent of rated heat capacity) and/or, for co-fired process heaters, different fuel mixtures (e.g., primarily gas fired, primarily oil fired, and equally co-fired, i.e., approximately 50 percent of the input heating value is from fuel gas and approximately 50 percent of the input heating value is from fuel oil). Performance tests for different operating ranges may be conducted at different times.

(B) Each test will consist of three test runs. Calculate the NOX concentration for the performance test as the average of the NOX concentrations from each of the three test runs. If the NOX concentration for the performance test is less than or equal to the numerical value of the applicable NOX emissions limit (regardless of averaging time), then the test is considered to be a valid test.

(C) If an operating curve is developed for different firing rates, conduct at least one test when the process heater is firing at no less than 70 percent of the rated heat capacity and at least one test under turndown conditions (i.e., when the process heater is firing at 50 percent or less of the rated heat capacity). If O2 operating limits are developed for co-fired process heaters based only on overall firing rates (and not by fuel mixtures), conduct at least one of the test runs for each test while the process heater is being supplied by both fuel gas and fuel oil and conduct at least one of the test runs while the process heater is being supplied solely by fuel gas.

(D) Determine the average O2 concentration for each test run of a valid test.

(E) Calculate the O2 operating limit for each operating range as the average O2 concentration of the three test runs from a valid test conducted at the representative conditions for that given operating range.

(F) Identify the firing rates for which the different operating limits apply. If only two operating limits are established based on firing rates, the O2 operating limits established when the process heater is firing at no less than 70 percent of the rated heat capacity must apply when the process heater is firing above 50 percent of the rated heat capacity and the O2 operating limits established for turndown conditions must apply when the process heater is firing at 50 percent or less of the rated heat capacity.

(G) Operating limits associated with each interval will be valid for 2 years or until another operating limit is established for that interval based on a more recent performance test specific for that interval, whichever occurs first. Owners and operators must use the operating limits determined for a given interval based on the most recent performance test conducted for that interval.

(7) The owner or operator of a process heater complying with a NOX limit in terms of lb/MMBtu as provided in § 60.102a(g)(2)(i)(B), (g)(2)(ii)(B), (g)(2)(iii)(B) or (g)(2)(iv)(B) or a process heater with a rated heat capacity between 40 and 100 MMBtu/hr that elects to demonstrate continuous compliance with a maximum excess O2 limit, as provided in § 60.107a(c)(6) or (d)(8), shall determine heat input to the process heater in MMBtu/hr during each performance test run by measuring fuel gas flow rate, fuel oil flow rate (as applicable) and heating value content according to the methods provided in § 60.107a(d)(5), (d)(6), and (d)(4) or (d)(7), respectively.

(8) The owner or operator shall use Equation 8 of this section to adjust pollutant concentrations to 0-percent O2 or 0- percent excess air.

(4)EPA Method 11, 15 or 15A of appendix A-5 to part 60 or EPA Method 16 of appendix A-6 to part 60 for determining the H2S concentration for affected facilities using an H2S monitor as specified in § 60.107a(a)(2). The method ANSI/ASME PTC 19.10-1981 (incorporated by reference - see § 60.17) is an acceptable alternative to EPA Method 15A of appendix A-5 to part 60. The owner or operator may demonstrate compliance based on the mixture used in the fuel gas combustion device or flare or for each individual fuel gas stream used in the fuel gas combustion device or flare.

(i) For Method 11 of appendix A-5 to part 60, the sampling time and sample volume must be at least 10 minutes and 0.010 dscm (0.35 dscf). Two samples of equal sampling times must be taken at about 1-hour intervals. The arithmetic average of these two samples constitutes a run. For most fuel gases, sampling times exceeding 20 minutes may result in depletion of the collection solution, although fuel gases containing low concentrations of H2S may necessitate sampling for longer periods of time.

(ii) For Method 15 of appendix A-5 to part 60, at least three injects over a 1-hour period constitutes a run.

(iii) For Method 15A of appendix A-5 to part 60, a 1-hour sample constitutes a run. The method ANSI/ASME PTC 19.10-1981, “Flue and Exhaust Gas Analyses,” (incorporated by reference - see § 60.17) is an acceptable alternative to EPA Method 15A of appendix A-5 to part 60.

(iv) If monitoring is conducted at a single point in a common source of fuel gas as allowed under § 60.107a(a)(2)(iv), only one performance test is required. That is, performance tests are not required when a new affected fuel gas combustion device or flare is added to a common source of fuel gas that previously demonstrated compliance.

40 CFR Part 60

Summary

The Environmental Protection Agency (EPA) is proposing to stay for three months certain requirements that are contained within the Final Rule titled “Oil and Natural Gas Sector: Emission Standards for New, Reconstructed, and Modified Sources,” published in the Federal Register on June 3, 2016 (2016 Rule). On June 5, 2017, the EPA published a notice that, in accordance with the Clean Air Act (CAA), the EPA stayed for three initial months the fugitive emissions requirements, well site pneumatic pump standards, and requirements for certification of closed vent systems by a professional engineer. The EPA granted reconsideration after considering specific objections to these requirements. In a separate notice published today, the EPA is proposing a stay for two years, providing the EPA sufficient time to propose, take public comment, and issue a final action on the issues concerning the specific requirements on which EPA has granted reconsideration. The two-year proposed stay published today, if finalized as proposed, would likely be determined to be a major rule under the Congressional Review Act and therefore will not take effect until sixty days after publication or after Congress receives the rule report, whichever is later. Therefore, while the EPA intends to complete that rulemaking and take final action before the initial three-month stay expires, there may potentially be a gap between the two stays due to the sixty-day delay in effectiveness of that action. To avoid such a potential gap, and the resulting confusion, in this action the EPA is proposing a three-month stay which would not qualify as a major rule and could become effective upon publication. The EPA prepared an Economic Impact Analysis for this proposal, which is available in Docket ID EPA-HQ-OAR-2017-0346. The EPA is seeking comment pertaining to this stay and its duration. The EPA is also seeking comment on if a four-month stay may be more appropriate to ensure continuity of the stay. The EPA is not taking comment at this time on substantive issues concerning these requirements, or on any of the other provisions subject to the reconsideration.

Comments must be received on or before July 17, 2017. If a hearing is requested on this proposed rule, written comments must be received on or before August 9, 2017. Public Hearing. A public hearing will be held, if requested by June 21, 2017, to accept oral comments on this proposed action. If a hearing is requested, it will be held at the EPA's Washington, DC campus located at 1201 Constitution Avenue NW., Washington, DC. The hearing, if requested, will begin at 9 a.m. (local time) and will conclude at 4 p.m. (local time) on July 10, 2017. To request a hearing, to register to speak at a hearing, or to inquire if a hearing will be held, please contact Aimee St. Clair at (919) 541-1063 or by email at stclair.aimee@epa.gov.

The Environmental Protection Agency (EPA) is proposing to stay for two years certain requirements that are contained within the Final Rule titled “Oil and Natural Gas Sector: Emission Standards for New, Reconstructed, and Modified Sources,” published in the Federal Register on June 3, 2016 (2016 Rule). On June 5, 2017, the EPA published a notice that it stayed for three months the; fugitive emissions requirements, well site pneumatic pump standards, and the requirements for certification of closed vent systems by a professional engineer in accordance with the Clean Air Act (CAA). The EPA has granted reconsideration based on specific objections to these requirements. The proposed stay discussed in this action, which follows the three-month stay, would provide the EPA sufficient time to propose, take public comment, and issue a final action on the issues concerning the specific requirements on which EPA has granted reconsideration. During this time, the EPA also plans to complete its reconsideration process for all remaining issues raised in these reconsideration petitions regarding fugitive emissions, pneumatic pumps, and certification by professional engineer requirements. The EPA acknowledges that the administrative reconsideration petitions include additional issues regarding these three requirements other than the issues for which we specifically have granted reconsideration. In addition, since the publication of the 2016 Rule, the EPA has received numerous questions relative to the implementation of these three requirements. During the reconsideration proceeding, the EPA intends to look broadly at the entire 2016 Rule. The EPA believes that addressing all of these issues at the same time would provide clarity and certainty for the public and the regulated community with regard to these requirements. The EPA is seeking comment pertaining to this stay and its duration and impact. The EPA is not taking comment at this time on substantive issues concerning these requirements, or on any of the other provisions subject to the reconsideration.

This final rule is effective June 2, 2017. The action granting reconsideration is effective June 2, 2017. The stay of §§ 60.5393a(b) through (c), 60.5397a, 60.5410a(e)(2) through (5) and (j), 60.5411a(d), 60.5415a(h), 60.5420a(b)(7), (8), and (12), and (c)(15) through (17) is effective from June 2, 2017, until August 31, 2017.

82 FR 21971 - Delegation of New Source Performance Standards and National Emission Standards for Hazardous Air Pollutants for the States of Arizona and Nevada

The Environmental Protection Agency (EPA) is proposing to approve updates to the Code of Federal Regulations delegation tables to reflect the current delegation status of New Source Performance Standards and National Emission Standards for Hazardous Air Pollutants in Arizona and Nevada.

The U.S. Environmental Protection Agency (EPA) announces that it is reviewing and, if appropriate, will initiate proceedings to suspend, revise or rescind the Standards of Performance for Greenhouse Gas Emissions From New, Modified, and Reconstructed Stationary Sources: Electric Generating Units.

The U.S. Environmental Protection Agency (EPA) announces it is reviewing the 2016 Oil and Gas New Source Performance Standards and, if appropriate, will initiate reconsideration proceedings to suspend, revise or rescind this rule.

The proposed rule published on October 23, 2015 entitled “Federal Plan Requirements for Greenhouse Gas Emissions From Electric Utility Generating Units Constructed on or Before January 8, 2014; Model Trading Rules; Amendments to Framework Regulations.” 80 FR 64966, and the proposed rule published on June 30, 2016 entitled “Clean Energy Incentive Program Design Details,” 81 FR 42940, are withdrawn as of April 3, 2017.

40 CFR Part 60

Summary

The U.S. Environmental Protection Agency (EPA) is withdrawing the October 23, 2015 proposals for a federal plan to implement the greenhouse gas (GHG) emission guidelines (EGs) for existing fossil fuel-fired electric generating units (EGUs), for model trading rules for implementation of the EGs, and for amendments to the Clean Air Act (CAA) 111(d) framework regulations, and the June 30, 2016 proposed rule concerning design details of the Clean Energy Incentive Program (CEIP).

Effective February 15, 2017, the EPA withdraws the direct final rule published at 81 FR 83160, on November 21, 2016.

40 CFR Part 60

Summary

Because the Environmental Protection Agency (EPA) received an adverse comment, we are withdrawing the direct final rule titled, “Revisions to Procedure 2—Quality Assurance Requirements for Particulate Matter Continuous Emission Monitoring Systems at Stationary Sources.”

This rule is effective on February 21, 2017 without further notice, unless the EPA receives adverse comment by December 21, 2016. If the EPA receives adverse comment, we will publish a timely withdrawal in the Federal Register informing the public that the rule will not take effect.

40 CFR Part 60

Summary

The Environmental Protection Agency (EPA) is taking direct final action to update a procedure in the New Source Performance Standards (NSPS). The procedure provides the ongoing quality assurance/quality control (QA/QC) procedures for assessing the acceptability of particulate matter (PM) continuous emissions monitoring systems (CEMS). The procedure explains the criteria for passing an annual response correlation audit (RCA) and the criteria for passing an annual relative response audit (RRA). The procedure currently contains a requirement that the annual QA/QC test results for affected facilities must fall within the same response range that was used to develop the existing PM CEMS correlation curve. As a result, some facilities are unable to meet the criteria for passing their annual QA/QC test because their emissions are now lower than the range previously set during their correlation testing. We are modifying the procedure to allow facilities to extend their PM CEMS correlation regression line to the lowest PM CEMS response obtained during the annual RCA or RRA, when these PM CEMS responses are less than the lowest response used to develop the existing correlation curve. This change will ensure that facilities that have reduced their emissions since completing their correlation testing will no longer be penalized because their lower emissions fall outside their initial response range. This action also corrects a typographical error in the procedure.

Written comments must be received by December 21, 2016. Public Hearing. If anyone contacts the EPA by December 1, 2016 requesting to speak at a public hearing on this action, the EPA will consider holding a public hearing on December 21, 2016 at the EPA facility in Research Triangle Park. Please check the EPA's Web page at https://www3.epa.gov/ttn/emc/proposed.html on December 12, 2016 for the announcement of whether a hearing will be held. To request a public hearing and present oral testimony at the hearing, please contact on or before December 1, 2016, the person listed in the FOR FURTHER INFORMATION CONTACT section of this document. If a hearing is held, the hearing schedule, including the list of speakers, will be posted on the EPA's Web page at https://www3.epa.gov/ttn/emc/proposed.html.

40 CFR Part 60

Summary

The Environmental Protection Agency (EPA) is proposing revisions to a procedure in the New Source Performance Standards (NSPS). The procedure provides the ongoing quality assurance/quality control (QA/QC) procedures for assessing the acceptability of particulate matter (PM) continuous emissions monitoring systems (CEMS). The procedure explains the criteria for passing an annual response correlation audit (RCA) and the criteria for passing an annual relative response audit (RRA). The procedure currently contains a requirement that the annual QA/QC test results for affected facilities must fall within the same response range as was used to develop the existing PM CEMS correlation curve. As a result, some facilities are unable to meet the criteria for passing their annual QA/QC test simply because their emissions are now lower than the range previously set during correlation testing. We are proposing to modify the procedure to allow facilities to extend their PM CEMS correlation regression line to the lowest PM CEMS response obtained during the RCA or RRA, when these PM CEMS responses are less than the lowest response used to develop the existing correlation curve. We also propose to correct a typographical error in the procedure.

The public comment period on the proposed rule published in the Federal Register on October 3, 2016 (81 FR 68110), is being extended. Written comments must be received on or before December 16, 2016.

40 CFR Parts 51, 52, 60, 70, and 71

Summary

On August 26, 2016, the Environmental Protection Agency (EPA) issued a proposed rule to revise provisions in the Prevention of Significant Deterioration (PSD) and title V permitting regulations applicable to greenhouse gases (GHGs) to fully conform with recent court decisions. The EPA is extending the comment period on this proposed rule that was scheduled to close on December 2, 2016. The EPA received a letter requesting the extension of the proposed rule public comment period to allow the public additional time to review the rule and supporting documentation.

This action provides notice that the U.S. Environmental Protection Agency (EPA) Administrator, Gina McCarthy, denied a petition for reconsideration of the final Standards of Performance for New Residential Wood Heaters, New Residential Hydronic Heaters and Forced-Air Furnaces published in the Federal Register on March 16, 2015.

2016-10-03; vol. 81 # 191 - Monday, October 3, 2016

81 FR 68110 - Revisions to the Prevention of Significant Deterioration (PSD) and Title V Greenhouse Gas (GHG) Permitting Regulations and Establishment of a Significant Emissions Rate (SER) for GHG Emissions Under the PSD Program

Comments must be received on or before December 2, 2016. If anyone contacts us requesting to speak at a public hearing by October 13, 2016, we will hold a public hearing. Additional information about the hearing would be published in a subsequent Federal Register notice.

40 CFR Parts 51, 52, 60, 70 and 71

Summary

The Environmental Protection Agency (EPA) is proposing to revise provisions applicable to greenhouse gases (GHG) in the EPA's Prevention of Significant Deterioration (PSD) and title V permitting regulations. This action is in response to the June 23, 2014, U.S. Supreme Court's decision in Utility Air Regulatory Group (UARG) v. EPA and the April 10, 2015, Amended Judgment by the United States Court of Appeals for the District of Columbia Circuit (D.C. Circuit) in Coalition for Responsible Regulation v. EPA. The proposed PSD and title V revisions involve changes to several regulatory definitions in the PSD and title V regulations, revisions to the PSD provisions on GHG Plantwide Applicability Limitations (PALs), and revisions to other provisions necessary to ensure that neither the PSD nor title V rules require a source to obtain a permit solely because the source emits or has the potential to emit (PTE) GHGs above the applicable thresholds. In addition, the EPA is also proposing a significant emissions rate (SER) for GHGs under the PSD program that would establish an appropriate threshold level below which Best Available Control Technology (BACT) is not required for a source's GHG emissions.

The public comment period for the proposed rule published in the Federal Register on June 30, 2016 (81 FR 42940), and extended at 81 FR 47325 (July 21, 2016) is being further extended. Written comments must be received on or before November 1, 2016.

40 CFR Part 60 and 62

Summary

On June 30, 2016, the Environmental Protection Agency (EPA) proposed a rule titled, “Clean Energy Incentive Program Design Details.” The EPA is extending the comment period on the proposed rule, which was scheduled to close on September 2, 2016, by 60 days until November 1, 2016. The EPA is making this change to allow for requested tribal consultation in response to the proposed rule.

The final rule is effective on October 31, 2016. The incorporation by reference materials listed in the rule are approved by the Director of the Federal Register as of October 31, 2016.

40 CFR Parts 51, 60, 61, and 63

Summary

This action promulgates technical and editorial corrections and revisions to regulations related to source testing of emissions. We have made corrections and updates to testing provisions, and added newly approved alternatives to existing testing regulations. These revisions will improve the quality of data and provide flexibility in the use of approved alternative procedures. The revisions do not impose any new substantive requirements on source owners or operators.

This final rule is effective on October 28, 2016. The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of October 28, 2016.

40 CFR Part 60

Summary

The Environmental Protection Agency (EPA) is finalizing a new subpart that updates the Emission Guidelines and Compliance Times for Municipal Solid Waste Landfills (Emission Guidelines). The EPA reviewed the landfills Emission Guidelines based on changes in the landfills industry since the Emission Guidelines were promulgated in 1996. The EPA's review of the Emission Guidelines for municipal solid waste (MSW) landfills considered landfills that accepted waste after November 8, 1987, and commenced construction, reconstruction, or modification on or before July 17, 2014. Based on this review, the EPA has determined that it is appropriate to revise the Emission Guidelines to reflect changes to the population of landfills and the results of an analysis of the timing and methods for reducing emissions. This action will achieve additional reductions in emissions of landfill gas and its components, including methane, by lowering the emissions threshold at which a landfill must install controls. This action also incorporates new data and information received in response to an advanced notice of proposed rulemaking and a proposed rulemaking and addresses other regulatory issues including surface emissions monitoring, wellhead monitoring, and the definition of landfill gas treatment system. The revised Emission Guidelines, once implemented through revised state plans or a revised federal plan, will reduce emissions of landfill gas, which contains both nonmethane organic compounds and methane. Landfills are a significant source of methane, which is a potent greenhouse gas pollutant. These avoided emissions will improve air quality and reduce the potential for public health and welfare effects associated with exposure to landfill gas emissions.

This final rule is effective on October 28, 2016. The incorporation by reference of certain publications listed in the regulations is approved by the Director of the Federal Register as of October 28, 2016.

40 CFR Part 60

Summary

The Environmental Protection Agency (EPA) is finalizing a new subpart that updates the Standards of Performance for Municipal Solid Waste Landfills. Under section 111 of the Clean Air Act, the EPA must review, and, if appropriate, revise standards of performance at least every 8 years. The EPA's review of the standards for municipal solid waste landfills considered landfills that commence construction, reconstruction, or modification after July 17, 2014. The final standards also reflect changes to the population of landfills and an analysis of the timing and methods for reducing emissions. This action will achieve additional reductions in emissions of landfill gas and its components, including methane, by lowering the emissions threshold at which a landfill must install controls. This action also incorporates new data and information received in response to the proposed rulemaking and addresses other regulatory issues including surface emissions monitoring, wellhead monitoring, and the definition of landfill gas treatment system. The new subpart will reduce emissions of landfill gas, which contains both nonmethane organic compounds and methane. Landfills are a significant source of methane, which is a potent greenhouse gas pollutant. These avoided emissions will improve air quality and reduce the potential for public health and welfare effects associated with exposure to landfill gas emissions.

The U.S. Environmental Protection Agency (EPA) is providing notice that it has responded to 11 petitions for reconsideration of the final rule titled “Oil and Natural Gas Sector: New Source Performance Standards and National Emission Standards for Hazardous Air Pollutants Reviews,” published in the Federal Register on August 16, 2012, and seven petitions for reconsideration of subsequent amendments published in the Federal Register on September 23, 2013, and December 31, 2014. The agency previously granted reconsideration of several discrete issues and took final action on reconsideration through documents published in the Federal Register on September 23, 2013, December 31, 2014, August 12, 2015, and June 3, 2016. The Administrator denied the remaining requests for reconsideration in separate letters to the petitioners. The basis for the EPA's action is set out fully in a separate document available in the rulemaking docket.

2016-08-08; vol. 81 # 152 - Monday, August 8, 2016

81 FR 52346 - Reconsideration on the Mercury and Air Toxics Standards (MATS) and the Utility New Source Performance Standards Startup and Shutdown Provisions; Final Action

The U.S. Environmental Protection Agency (EPA) is providing notice that it has responded to two petitions for reconsideration of the final rule titled “Reconsideration of Certain Startup/Shutdown Issues: National Emission Standards for Hazardous Air Pollutants (NESHAP) From Coal- and Oil-Fired Electric Utility Steam Generating Units and Standards of Performance (NSPS) for Fossil-Fuel-Fired Electric Utility, Industrial-Commercial-Institutional, and Small Industrial-Commercial-Institutional Steam Generating Units,” published in the Federal Register on November 19, 2014. The Administrator denied the requests for reconsideration in separate letters to the petitioners. The letters and a document providing a full explanation of the agency's rationale for each denial is in the docket for these rules.

The public comment period for the proposed rule published in the Federal Register on June 30, 2016 (81 FR 42940), is being extended. Written comments must be received on or before September 2, 2016.

40 CFR Parts 60 and 62

Summary

On June 30, 2016, the Environmental Protection Agency (EPA) proposed a rule titled, “Clean Energy Incentive Program Design Details.” The EPA is extending the comment period on the proposed rule that was scheduled to close on August 29, 2016, by four days until September 2, 2016. The EPA is making this change to align the public comment period with the public hearing submittal time frame.

This action amends the National Emissions Standards for Hazardous Air Pollutants (NESHAP) for Petroleum Refineries in three respects. First, this action adjusts the compliance date for regulatory requirements that apply at maintenance vents during periods of startup, shutdown, maintenance or inspection for sources constructed or reconstructed on or before June 30, 2014. Second, this action amends the compliance dates for the regulatory requirements that apply during startup, shutdown, or hot standby for fluid catalytic cracking units (FCCU) and startup and shutdown for sulfur recovery units (SRU) constructed or reconstructed on or before June 30, 2014. Finally, this action finalizes technical corrections and clarifications to the NESHAP and the New Source Performance Standards (NSPS) for Petroleum Refineries. These amendments are being finalized in response to new information submitted after these regulatory requirements were promulgated as part of the residual risk and technology review (RTR) rulemaking, which was published on December 1, 2015. This action will have an insignificant effect on emissions reductions and costs.

The Environmental Protection Agency (EPA) is finalizing amendments to the standards of performance for stationary compression ignition (CI) internal combustion engines to allow manufacturers to design the engines so that operators can temporarily override performance inducements related to the emission control system for stationary CI internal combustion engines. The amendments apply to engines operating during emergency situations where the operation of the engine or equipment is needed to protect human life, and to require compliance with Tier 1 emission standards during such emergencies. The EPA is also amending the standards of performance for certain stationary CI internal combustion engines located in remote areas of Alaska.

Comments. Comments must be received on or before August 29, 2016. Public Hearing. The EPA will hold one public hearing on the CEIP design details proposed rule. The hearing will be held to accept oral comments on the proposal. The hearing will be held in Chicago, Illinois, on August 3, 2016. The hearing will begin at 9:00 a.m. Central Standard Time CST and will conclude at 8:00 p.m. (CST). There will be a lunch break from 12:00 p.m. to 1:00 p.m. and a dinner break from 5:00 p.m. to 6:00 p.m.

40 CFR Parts 60 and 62

Summary

In this action, the Environmental Protection Agency (EPA) is proposing design details of the Clean Energy Incentive Program (CEIP). The CEIP is a program that states have the option to adopt if they wish to incentivize certain early emission reduction projects under the Carbon Pollution Emission Guidelines for Existing Stationary Sources: Electric Utility Generating Units (also known as the Clean Power Plan Emission Guidelines (EGs)). The framework for the CEIP was established in the Clean Power Plan EGs, where the EPA also noted that the design details of the program would be developed in a follow-on action. This proposal addresses those design details. In addition, we are re-proposing the CEIP-related aspects of the proposed rate-based and mass-based model trading rules—referred to in this action as optional example regulatory text. This proposal is consistent with the Supreme Court's orders staying the Clean Power Plan during judicial review. The timing elements of the CEIP may be adjusted, if necessary, upon resolution of the petitions for review of the Clean Power Plan.

The amendments in this rule to 40 CFR part 60, subpart DDDD, are effective June 23, 2016, and to 40 CFR part 60, subpart CCCC, are effective December 23, 2016. The incorporation by reference of certain publications listed in this rule was approved February 7, 2013.

40 CFR Part 60

Summary

This action sets forth the Environmental Protection Agency's (EPA) final decision on the issues for which it granted reconsideration on January 21, 2015, which pertain to certain aspects of the February 7, 2013, final rule titled “Standards of Performance for New Stationary Sources and Emissions Guidelines for Existing Sources: Commercial and Industrial Solid Waste Incineration Units” (CISWI rule). The EPA is finalizing proposed actions on these four topics: Definition of “continuous emission monitoring system (CEMS) data during startup and shutdown periods;” particulate matter (PM) limit for the waste-burning kiln subcategory; fuel variability factor (FVF) for coal-burning energy recovery units (ERUs); and the definition of “kiln.” This action also includes our final decision to deny the requests for reconsideration of all other issues raised in the petitions for reconsideration of the 2013 final commercial and industrial solid waste incineration rule for which we did not grant reconsideration.

This final rule is effective on August 2, 2016. The incorporation by reference (IBR) of certain publications listed in the regulations is approved by the Director of the Federal Register as of August 2, 2016.

40 CFR Part 60

Summary

This action finalizes amendments to the current new source performance standards (NSPS) and establishes new standards. Amendments to the current standards will improve implementation of the current NSPS. The new standards for the oil and natural gas source category set standards for both greenhouse gases (GHGs) and volatile organic compounds (VOC). Except for the implementation improvements, and the new standards for GHGs, these requirements do not change the requirements for operations covered by the current standards.

This rule is effective on August 17, 2016 without further notice, unless the EPA receives adverse comment by July 5, 2016. If the EPA receives adverse comment, we will publish a timely withdrawal in the Federal Register informing the public that the rule will not take effect.

40 CFR Part 60

Summary

The Environmental Protection Agency (EPA) is taking direct final action to make several minor technical amendments to the performance specifications and test procedures for hydrogen chloride (HCl) continuous emission monitoring systems (CEMS). This direct final rule also makes several minor amendments to the quality assurance (QA) procedures for HCl CEMS used for compliance determination at stationary sources. The performance specification (Performance Specification 18) and the QA procedures (Procedure 6) were published in the Federal Register on July 7, 2015. These amendments make several minor corrections and clarify several aspects of these regulations.

Comments: Written comments must be received by July 5, 2016. Public Hearing. The EPA will hold a public hearing on this rule if requested. Requests for a hearing must be made by May 24, 2016. Requests for a hearing should be made to Ms. Candace Sorrell via email at sorrell.candace@epa.gov or by phone at (919) 541-1064. If a hearing is requested, it will be held on June 3, 2016 at the EPA facility in Research Triangle Park, NC.

40 CFR Part 60

Summary

The Environmental Protection Agency (EPA) is proposing to make several minor technical amendments to the performance specifications and test procedures for hydrogen chloride (HCl) continuous emission monitoring systems (CEMS). The EPA is also proposing to make several minor amendments to the quality assurance (QA) procedures for HCl CEMS used for compliance determination at stationary sources. The performance specification (Performance Specification 18) and the QA procedures (Procedure 6) were published in the Federal Register on July 7, 2015. These proposed amendments make several minor corrections and clarify several aspects of these regulations. In the “Rules and Regulations” section of this Federal Register, the EPA is amending Performance Specification 18 and Procedure 6 as a direct final rule without a prior proposed rule. If we receive no adverse comment, we will not take further action on this proposed rule.

This action finalizes the technical corrections that the Environmental Protection Agency (EPA) proposed on February 17, 2015, to correct and clarify certain text of the EPA's regulations regarding “National Emission Standards for Hazardous Air Pollutants from Coal- and Oil-fired Electric Utility Steam Generating Units and Standards of Performance for Fossil-Fuel-Fired Electric Utility, Industrial-Commercial-Institutional, and Small Industrial-Commercial-Institutional Steam Generating Units”. We are also taking final action to remove the rule provision establishing an affirmative defense for malfunction.

This action proposes amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) Refinery MACT 1 and Refinery MACT 2 regulations and the New Source Performance Standards (NSPS) for petroleum refineries, which were published on December 1, 2015. In that action, as a result of a risk and technology review, the Environmental Protection Agency (EPA) finalized amendments to Refinery MACT 1 and Refinery MACT 2. In this action, the EPA is proposing to amend the compliance date in Refinery MACT 1 for maintenance vent standards that apply during periods of startup, shutdown, maintenance or inspection for sources constructed or reconstructed on or before June 30, 2014. In this action, the EPA is also proposing to revise the compliance dates in Refinery MACT 2 for the standards that apply during startup, shutdown, or hot standby for fluid catalytic cracking units (FCCU) and startup and shutdown for sulfur recovery units (SRU) constructed or reconstructed on or before June 30, 2014. These proposed revisions do not affect requirements that apply during normal operations. Finally, the EPA is proposing technical corrections and clarifications to the NESHAP and the NSPS for petroleum refineries. This action will have an insignificant effect on emissions reductions and costs.

This final action is effective on February 1, 2016. The incorporation by reference of certain publications for part 63 listed in the rule is approved by the Director of the Federal Register as of February 1, 2016. The incorporation by reference of certain publications for part 60 listed in the rule were approved by the Director of the Federal Register as of June 24, 2008.

40 CFR Part 60

Summary

This action finalizes the residual risk and technology review conducted for the Petroleum Refinery source categories regulated under national emission standards for hazardous air pollutants (NESHAP) Refinery MACT 1 and Refinery MACT 2. It also includes revisions to the Refinery MACT 1 and MACT 2 rules in accordance with provisions regarding establishment of MACT standards. This action also finalizes technical corrections and clarifications for the new source performance standards (NSPS) for petroleum refineries to improve consistency and clarity and address issues related to a 2008 industry petition for reconsideration. Implementation of this final rule will result in projected reductions of 5,200 tons per year (tpy) of hazardous air pollutants (HAP) which will reduce cancer risk and chronic health effects.
